test(codex): expect the neutral JSON reply in the Windows hook test

The managed Codex hook now answers with `{}` on every path, POSIX and
Windows alike. The POSIX test was updated with that change; this one
was not, because it is skipped off Windows and only runs inside the
packaging job, so a local suite run stays green either way.

Expect the neutral reply where the script actually runs. The
script-removed case keeps an empty stdout: the echo cannot run when
the script is gone.
